  DISPLAY
   This case concerns simple 2D flow with additional pressure
   drop, introduced into  the flow by  means of a  PATCH and
   COVAL statement  for a  velocity component.  That type of
   patches can be used to model flow through a media with  a
   local resistance to the flow.

   The main objective of the test case is to demonstrate the
   new feature implemented in CCM, as well as MBFGE  method,
   which enables to introduce the pressure drop in the  same
   way as for staggered algorithm (LCCM=F).

   User is  advised to  study the  way in  which a  pressure
   drop is introduced in the  Q1 (ITEST= 1 or ITEST=  2) and
   investigate this  feature by  modifying the  direction of
   the flow on vertical by setting LRTFL to F.
